JOSEPH BLOOM, OF NEW YORK, N. Y.

STITCHER-WHEEL DRIVE.

Application filed August '24, 1923.

To all whom it may concern:

Be it known that I, JosnrH BLOOM, a citizens of the United States, and a resident of the city of New York, borough of the Bronx, in the county of Bronx andState of New York, have invented a new and Improved Stitcher-Vheel Drive, of which the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in knitting machines, and it pertains more particularly to knitting machines of the circular type.

In machines of this character as commonly constructed there is an element known as a stitcher wheel, and said stitcher wheel has vanes or blades which pass between the needles of the circular series commonly employed in these machines. The stitcher wheel in generally driven by the interengagement of its blades of vanes with the needles of the circular series.

It is one of the primary objects of the invention to provide a new and improved driving means for stitcher wheels whereby the stitcher wheel will be positively driven through a train of gearing.

It is a further object of the invention to construct the drive so that the train of gearing is operated directly from the needles of the circular series.

With the above and other objects in view, reference is had to the accompanying drawings, in which Figure 1 is a fragmentary view of a circular series of needles employed in a circular knitting machine showing a portion of the driving mechanism in section;

Figure 2 is a fragmentary plan view.

Referring more particularly to the drawings, the reference character 5 designates the needles of the circular series, and such needles are secured by means of clamping bolts 6 in a frame of ring-like form designated by the reference character 7. The stitcher wheel 8, as heretofore stated, comprises a plurality of vanes adapted as indicated at X in 2, to pass between the needles 5 of the circular series. This stichter wheel is mounted upon a stub shaft 10 carried by an arm 11, and such arm in turn is supported by means of a shaft 12 secured in a suitable bracket carried by the frame of the machine and not shown in the present instance. Secured to the arm 11 is a substantialy L-shaped frame 13, and said frame Serial No. 659,219.

is preferably secured to the arm 11 by means of the stub shaft 10.

Mounted on the stub shaft 10 heretofore mentioned at a point above the stitcher wheel 8, there is a gear 14, which gear meshes with a gear 15 carried by a shaft 16 mounted in the L-shaped frame 13. The gear 15 is secured to the shaft 16 to rotate therewith, by means of a pin, or the like, 17. Secured to the L-shaped frame 13, by means of bolts, screws, or the like, 18,.is an arm 19, and such arm is bent, as at 20, to provide an angularly disposed projecting end 21. Mounted in the projecting end 21, by means of a stub shaft, or the like, 22, there is a multiple gear 23, having straight teeth 24 and beveled teeth 25. The beveled teeth 25 are adapted to engage a gear 26 carried by the shaft 16 heretofore mentioned, while the straight teeth 24 of the gear 23 are adapted to pass between the needles 5, as shown at Y in Fig. 2, said needles serving the means for rotating the gear 23.

The device operates in the following manner:

As the machine is started and the circular series of needles starts to move in a circular path, the needles drive the gear 23 by engagement with the teeth 24 thereof. As the gear 23 is driven, throughthe me=' dium of its beveled teeth 25 the gear 26 is driven and through the medium of the shaft 16 the gear 26 drives the gear 15.

The gear 15 meshing with the gear 14 drives the same and through the medium of the gear 14 the stub shaft 10 is driven to drive the stitcher wheel 8.

From the foregoing it is apparent that as the needles are driven in a circular path, the stitcher wheel 8 is positively driven through the medium of the train of gearing, and the several blades of the stitcher wheel are caused to pass between the needles 5 and the stitcher wheel is driven independently of the interengagement of the blades with the needles of the circular series.

What is claimed is:

1. A stitcher wheel drive for use in combination with circular knitting machines and comprising a supporting member, a bracket carried by the supporting member, a plurality of shafts mounted in said bracket, astitcher wheel, and a gear wheel carried by one of said shafts, a plurality of gear wheels carried by the other of said shafts, one of which meshes with the first-mentioned and shaft.

gear Wheel, a second bracket carried by the first-mentioned bracket, and a gear wheel carried by the second-mentioned bralcket and meshing With the needles of the circular machine and With the other of the gears carried by the second-mentioned shaft for driving the stitcher Wheel through the train of gearing comprising said gears e10 shaft, a gear meshing With said last-mentioned gear and with the needles of the circular series of said machine, and means for supporting said last-mentioned gear.

3. A device of the character described comprising a bracket, means for supporting the bracketin proximity to the circular needle series of a circular machine, a pair of shafts carried by said bracket and in parallel relation, a gear and a stitcher Wheel carried by one of said shafts, a gear car ried by the other shaft and meshing With the gear carried by the firstmentioned shaft, a second gear carried by the second-mentioned shaft, a gear meshing with said lastmentioned gear and With the needles of the circular series of said machine, and means for supporting said last-mentioned gear, said supporting means comprising an angular arm carried by said bracket.
